0–100, higher is better. How it is calculated

illumos.org is the official website for the illumos open source Unix operating system project. The project provides advanced system debugging, next generation filesystem, networking, and virtualization features for downstream distributions. It is developed by a community of volunteers and companies, targeting developers and organizations interested in Unix-based operating systems. The website serves as a hub for downloads, source code access, community engagement, and documentation. Technically, the site is built with clean HTML and CSS, is mobile responsive, and uses minimal external dependencies, reflecting a lightweight and efficient design. Security posture is moderate with domain transfer protection and HTTPS assumed but lacks DNSSEC and security headers. Privacy compliance is limited, with no cookie or privacy policies explicitly presented. Overall, the site is trustworthy, professional, and safe for general audiences, but could improve in security and privacy transparency.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

7 findings rated critical or high. Fix these first.

  1. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The illumos project occupies a niche position in the open source operating system market, providing a Unix base for various downstream distributions. Its business model is community-driven with corporate contributions, focusing on technology development rather than commercial sales. The target audience includes developers, system administrators, and technology companies seeking a robust Unix OS foundation. The project benefits from a stable domain registration since 2010 and a consistent brand presence. Partnerships are implied through linked distributions like OmniOS and OpenIndiana. The project emphasizes inclusivity and community governance, supported by a code of conduct and active mailing lists. Revenue streams are not explicit, typical for open source projects relying on community and corporate sponsorships.

Security posture

The website demonstrates a moderate security posture. The domain is protected against unauthorized transfers, but DNSSEC is not enabled, which could improve DNS security. No security headers were detected in the provided data, and no explicit incident response or security policies are published on the site. The absence of cookie and privacy policies suggests limited privacy compliance. No vulnerabilities or exposed sensitive data were found in the content. The site does not use tracking or analytics scripts, reducing privacy risks. Incident response readiness and security culture indicators are not visible. Overall, the security posture is adequate for an open source project website but could be enhanced by adopting modern security headers, DNSSEC, and publishing security policies.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to improve site security.
  3. Publish explicit privacy and cookie policies, including GDPR compliance statements if applicable.
  4. Add clear contact information and incident response contacts to improve trust and security readiness.
  5. Consider adding a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.

  4. No forms detected on the homepage content.
  5. The site uses minimal external scripts and no analytics or tracking detected.
  6. The site is mobile responsive and uses a clean, simple design.

Technical notes

Notes

The website uses a simple and clean technical stack primarily consisting of HTML5 and CSS with the Tachyons framework for styling. The site is mobile responsive and optimized for different screen sizes. No CMS or complex frameworks are detected, indicating low technical debt and ease of maintenance. Hosting details are not explicit but the domain registrar is known and reputable. Performance is moderate given the minimalistic design and lack of heavy scripts. SEO is basic with meta tags present but no advanced structured data or Open Graph tags detected. Accessibility is basic but could be improved with ARIA roles and landmarks. No analytics or tracking scripts are used, which benefits privacy but limits marketing insights.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
